Answer in brief
CVE-2022-50746 records a High severity (CVSS 8.4) vulnerability in erofs: validate the extent length for uncompressed pclusters. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 8.4. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

The first issue has already been addressed. This patch addresses the second issue by checking the extent length validity.
